COAL-BARGE.

SPECIFICATION forming part of Letters Patent No. 494,121, dated March28, 1893.

Application filed August 16, 1888- Serial No. 282,838. (No model.)

To all whom it may concern:

Be it known that I, JONATHAN CHASE, of Boston, county of Suffolk, Stateof Massachusetts, have invented an Improvement in Coal Barges orVessels, of which the following description, in connection with theaccompanymg drawings, is a specification,like letters on I well a andhaving secured to its upper end,

the drawings representing like parts.

This invention relates to barges or vessels especially adapted for thetransportation of 5 coal and other granular material, and has for itsobject to provide a barge or vessel with an elevating mechanism as willbe described,

whereby the coal or other material in thebarge or vessel may be rapidlydischargedets being shaped as shown in Figs. 4 and 5,

therefrom with substantially little labor.

My invention therefore consists essentially in the combination withabarge or vessel pro-i vided with a passage-way extended length-i; wiseof the vessel and communicating with; its deck, of an upright frame, anda continug ous or endless chain of buckets extended E through the saidpassage-way and over thei' said upright frame, substantially as will be:

5 pulley c on the shaft 0 of the sprocket wheel described and claimed.

Other features of my invention will be pointed out in the claims at theend of this 2 as herein shownby steam from a boiler 0 specification.

Figure 1 is a longitudinal section of a barge or vessel provided with anelevating mechanism in accordance with my invention; Fig. 2 f atransverse section of Fig. l on line 0;, 00,- Fig. 1, looking toward theright; Fig. 3 a;

transverse section of the barge shown in Fig.

1 on line a, 41:, looking toward the left, and Z Figs. 4 and 5 detailsto more clearly show the construction of the buckets.

The barge or vessel a which may be of any ordinary construction such asnow commonly employed for transporting coal, is provided near itsopposite ends with'elevator wells 0. 0. extended from the deck to nearthe bottom of the vessel. The elevator wells communicate with each otherby passage way a formed as herein shown by a false bottom preferablymade in two parts a a see Fig. 3, which incline toward the longitudinalcenter of the vessel. The inclined parts a a forming the false bottom,do not come together, but'are separated to leave adischarge mouth oropening a which is closed as herein shown by a series of doors of,hinged to the parts a a and held closed by chains a secured it may be toshafts or rods a supported above the deck, the said doors openingdownward as herein shown.

The barge or vessel supports'an upright frame 6 herein shown as extendedinto the side rails b which are extended to the elevator well a. Theelevator wells a a have located in them near their bottoms, sprocketWheels b b and the upright frame supports a sprocket wheel b Thesprocket wheels b b have passed about them an endless chain of buckets band troughs b the said buckb and a pulley c on the shaft of an engine '0carried by the barge or vessel, and driven The shaft of each sprocketwheel is preferably provided with a pulley, and the said pulleys areconnected by belts whereby the strain is relieved fromthe endless chainof buckets. The endless chain of buckets is made to travel in thedirection of arrow 20, and those buckets passing through the passage waya beneath the doors, are filled with the coal or other granular materialcarried by the barge; the said coal falling into the troughs and fromthe troughs into the buckets when the said troughs are moved into anupright position, that is, when they have passed by the sprocket wheelsIf. The coal elevated by the buckets, is discharged therefrom as thesaid buckets pass over the shaft of the sprocket wheels 5 the said coalbeing dischargedas herein shown into a chute d supported from theupright frame, and provided as shown with a discharge nozzle or 1 gooseneck id free to be swung in a circle to discharge the coal from the sideof the barge into any suitable hopper or chute. The shaft or arbor 11will preferably be provided with wheels d on opposite sides of thebuckets which run on tracks 01 located in the passage way, see Fig. 3,and secured to the inclined side rails b, the said wheels diminishingthe friction and thereby obtaining an easier working apparatus.

In order that a portion of the cargo may be discharged, I have providedauxiliary doors or knives d movable in guides 01 secured as shown to theunderside of the false bottom, each of the said knives being operated asherein shown by aworm gear d in mesh with a rack bar at secured to orforming part of the said knife, the said worm gear being driven by aworm d on a shaft 01 herein shown as driven by a shaft 01 provided witha bevel gear (1 in engagement with a bevel gear 01 on the shaft d.

To take up'any coal which may fall below the buckets, I have providedone or more projections or brushesesecured to the underside of theendless chain of buckets.

The sprocket wheels are provided with fingers e at given distances aparton their peripheries, to engage the hubs b on the troughs, the bucketsand troughs being located between said wheels so that the load is withinthe circumference of the sprocket wheels.

It will be noticed that the bottom of each bucket is substantially on aline with the circumference of the sprocket wheels, so that ing thebuckets as described, the said buckets are brought into correct positionbelow the doors of the barge to permit the coal to drop 1 directly intothem. This is an important feature when coal and like material which ishard and would resist the scooping action of 3 outwardly hung buckets,is to be elevated.

To adapt my improved elevator mechanism to barges or vessels as nowcommonly constructed having a substantially high keelson, the inclinedparts a a may be made longer or shorter as desired, to bring thedischarge mouth or passage at one side of the longitudinal center of thebarge or vessel,but 1 do not desire to limit myself to the use of afalse bottom composed of inclined sides for forming the passage way a Iclaim- 1. The combination, with a barge or vessel provided with elevatorwells a a at or near its opposite ends, and a false bottom forming apassage way to connect the said elevator wells, a sprocket wheel locatedin each elevator well, an upright frame, and a sprocket wheel supportedthereby, of an endless chain of buckets extended through said elevatorwells and passage way, and means to rotate said sprocket wheels to causethe endless chain of buckets to travel, substantially as and for thepurpose specified.

2. The combination with a barge or vessel provided with elevator wells0. a? at or near its opposite ends, and a false bottom composed ofinclined parts a a forming a passage way to connect the said elevatorwells, doors a hinged to the parts, and connections to operate saiddoors from above the deck, and an upright frame, of an endless chain ofbuckets, and sprocket wheels about which the endless chain is passed,and means to drive said endless chain of buckets, substantially asdescribed.

3. The combination with a barge or vessel provided with elevator wells a0. at or near its opposite ends, and inclined parts a a. forming apassage way to connect said elevator wells, of an upright frame extendedabove the deck of the barge or vessel, side rails 19 extended from theframe to the elevator well a, sprocket wheels located in said elevatorwells and on said frame, and an endless chain of buckets passed aboutsaid sprocket wheels and adapted to travel through said elevator wellsand passage way, as and for the purpose specified.
